Protocol - Tobacco - 30-Day Quantity and Frequency - Adolescent
Measures used to calculate the respondent’s 30-day quantity and frequency use of cigarettes. For the adolescent respondent, there is one set of questions
All adolescent respondents are asked if they smoked in the last 30 days. If the respondent has smoked during the past 30 days, he or she is asked to report the quantity and frequency of cigarette smoking.
The Working Group acknowledges that the following questions may gather sensitive information relating to the use of substances and/or illegal conduct. If the information is released it might be damaging to an individual’s employability, lead to social stigmatization, or other consequences.

[ ] 1 Yes
[ ] 2 No
If Question 1 is "Yes," then ask:
2a. During the past 30 days, that is, since [DATEFILL*], on how many days did you smoke part or all of a cigarette?
# OF DAYS: ____ [RANGE: 1 - 30]
Don’t Know / Refused
If Question 2a is "Don’t know" or "Refused," then ask:
2b. What is your best estimate of the number of days you smoked part or all of a cigarette during the past 30 days?
[ ] 1 1 or 2 days
[ ] 2 3 to 5 days
[ ] 3 6 to 9 days
[ ] 4 10 to 19 days
[ ] 5 20 to 29 days
[ ] 6 All 30 days
[ ] Don’t Know / Refused
3. On the [NUMBER OF DAYS REPORTED IN 2a OR 2b] you smoked cigarettes during the past 30 days, how many cigarettes did you smoke per day, on average?
[ ] 1 Less than one cigarette per day
[ ] 2 1 cigarette per day
[ ] 3 2 to 5 cigarettes per day
[ ] 4 6 to 15 cigarettes per day (about 1/2 pack)
[ ] 5 16 to 25 cigarettes per day (about 1 pack)
[ ] 6 26 to 35 cigarettes per day (about 1 1/2 packs)
[ ] 7 More than 35 cigarettes per day (about 2 packs or more)

* DATEFILL is the date 30 days prior to the date of the interview.
Protocol Name from Source:
National Survey on Drug Use and Health (NSDUH)
Personnel and Training Required
Interviewer must be trained and found competent to conduct personal interviews with individuals from the general population. The interviewer should be trained to prompt respondents further if a "don’t know" response is provided.
While the source instrument was developed for administration by computer, the PhenX Expert Review Panel acknowledges that these questions can be administered in a noncomputerized format.
|Specialized requirements for biospecimen collection||No|
|Average time of greater than 15 minutes in an unaffected individual||No|
Mode of Administration
The protocol from the National Survey on Drug Use and Health (NSDUH) was selected because this survey is the primary combined source of information on the use of drugs, alcohol, and tobacco in the civilian, noninstitutionalized population of the United States. The study was initiated in 1971, and it is currently conducted on an annual basis. The NSDUH is a survey that includes all substance use and that is administered to individuals age 12 and older. This survey asks many additional questions that may be more relevant to investigators studying adolescent subjects.

Process and Review
The Expert Review Panel #3 (ERP 3) reviewed the measures in Alcohol, Tobacco and Other Substances, and Substance Abuse and Addiction domains.
Guidance from ERP 3 includes:
• Updated protocol
• New Data Dictionary
Back-compatible: Partially back-compatible (updated/similar protocol which would require some changes to the data dictionary), variable mapping between current and previous protocols can be found here.

Tobacco - 30-Day Quantity and Frequency
November 21, 2016
Questions asking the respondent about quantity and frequency of cigarette smoking during the past 30 days.
This measure can be used to assess the participant’s exposure to cigarette smoking. The potential of recall bias can be reduced by assessing the respondent’s recent use.
